# 3 Way Switch Wiring Diagram Power At Switch

### Then a 4 wire cable going between the two 3 way switches and then a 3 wire cable going from the switches to the load.

3 way switch wiring diagram power at switch. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. To illustrate the wiring of these 3 way switches switch boxes and fixture boxes are not shown but are obviously required for every application. With these diagrams below it will take the guess work out of wiring. Remember only two wire cable with ground is necessary for the boxes at the lights we see there.

Run new cable romex between the 3 way switches. Typical 3 way switch wiring nm cable. Pick the diagram that is most like the scenario you are in and see if you can wire your switch. 3 way switch wiring diagram.

Traveller wires red in color connect the three way switches without going in deep to the system or circuit given. If you are trying to troubleshoot a 3 way switch operation you will need to identify the function of each wire. Actually the diagram explains everything clearly while controlling by two 3 way switches with a two wire cable power supply as shown. When wiring a 3 way switch circuit we will be using a 3 wire cable known as romex coming from the source such as the breaker box.

Traveler wires are interchangeable. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. A 3 wire nm connects the traveler terminals of the first and second 3 way switch together.

Wiring a 3 way light switch. Take a closer look at a 3 way switch wiring diagram. Wires consisting of a line a load a neutral a pair of travelers and two 3 way switches. Each 3 way switch in these examples are controlling the power source to the same load.

The black line wire connects to the common terminal of the first 3 way switch. All three way switch and 2 way switch wiring diagrams have the same basic components. The travelers actually pass the electricity between the two 3 way switches as well as the 4 way switches shown in the 4 way switching wiring diagrams. This might seem intimidating but it does not have to be.

In the 1st diagram below a 2 wire nm cable supplies power from the panel to the first switch box. So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire.
